CHAIN-HOOK.

Specification of Letters Patent.

Patented July 10., 1906.

Application filed March 22. 1906-. Serial No. 307.368.

T0 aZZ whom it may concern:

Be it known that l, GUs'rAv KERNIN, a citizen of the United States, anda resident of Crandon, in the county of Forest and State of WVisconsin,have invented certain new and useful Improvements in Chain-Hooks; and Ido hereby declare that the following is a full, clear, and exactdescription thereof.

My invention refers to chain-hooks especially designed in connectionwith bindingchains for tieing logs together for transportation, itsobject being to provide a hook which is capable of being securelylocked, with means for readily attaching thereto a lanyard whereby saidhook may be unlocked or opened at a safe distance from the load, so thataccidents from the falling logs are effectually avoided, said accidentsbeing common in logging industries, due to the fact that withchain-hooks of the usual type it is necessary for the operator to standwithin reaching distance of the same when the chain is to be releasedfrom a load of logs.

Said invention consists in certain peculiarities of construction andcombination of parts, as fully set forth hereinafter with reference tothe accompanying drawings and subsequently claimed.

In the drawings, Figure 1 represents a chain-hook made in accordancewith my invention, the hook being shown in locked position in connectionwith an end of a logchain, its open position being illustrated in dottedlines. Said view also shows the ununlocking -lanyard attached thereto;and Fig. 2 a cross-section of the same, as indicated by line 2 2 of Fig.1.

Referring by letter to the drawings, A indicates a bar having pivotedthereto at one end a latch member B, the free end of which when lockedrests against the edge of the bar and is held in this position by alocking-lever O, which lever is fulcrumed at its upper end on a pin a,secured in ears I) b, riveted to the said bar. The free end of the latchB is formed with a curved nose flattened at its end, the outer curve aof the nose being struck on a radius from the locking-lever fulcrum,which lever has its short arm (1 similarly curved to nest with the curve0 of the nose the lower end of said curve portion 01 being provided witha stop-lug e, arranged to abut the flattened end of the latch-membernose when said latch is locked. The long arm of the locking-leverterminates in a scroll-loop f, which is provided for the reception of aring 9 of one member of a grapple D, the other member being arrangedwith a hook for engagement with the inner edge of the latch-nose. Thegrapple members are centrally connected by a loop, to which is secured alanyard E, which is of any desired length, for the purpose of releasingthe chainhook lock.

As shown in Fig. 1 of the drawings, the end link of a log-chain F isgripped in a throat formed between the latch and bar of the chain-hook.The other end of said chain (not shown) may be either fast to the sideof a vehicle or, if desired, connected direct to the opposite end of thebar A; but in this instance said bar is shown as having a short chainsection G connected thereto through an opening 72,, said section beingfor the purpose of attaching the hook to a car or other vehicle, whilethe log-chain F is secured to the opposite side thereof and is fast overthe load of logs and gripped, as,shown. The chain section G, as shown,may also be linked into the scroll of the lever, so as to provideadditional safeguard against the unlocking of the device in transit, inwhich case it would be necessary to uncouple the same from said scrollbefore the lever C could be actuated to release the load. To release thehook, the operator adjusts the grapple to the position shown in thedrawings and uncouples the chain-section G from the locking-lever, andthereafter moves to a safe distance and pulls the lanyard, whichmovement causes said locking-lever to assume the position as indicatedby dotted lines, which position frees the latch, a further pull causingthe same to open and free the end of log-chain from the throat. It isobvious, however, that said grapple may be connected to the lever Conly, in whic case the strain of the load upon the log-chain would berelied upon to open the latch B, and, further, while I have shown anddescribed the lanyard in connection with a detachable grapple saidlanyard may be, if desired, permanently attached to the lever. Thearrangement of chains and their connections are immaterial to theessential features of my invention, which lie in the provision forlooking the chain-hook in such a manner that short arm curved andterminating in a stoplug for engagement with the free end of the latch;and a grapple for connection with the aforesaid latch and long arm ofthe lockinglever.

3. A chain-hook comprising a bar, a latch in pivotal connectiontherewith, the free end 20 of which is provided with a curved arm, alocking-lever pivoted to the bar having its short arm curved andterminating. in a stoplug for engagement with the free end of the latch,means in connection with the free ends of the aforesaid locking leverand bar, whereby they are coupled, and a grapple adapted to be connectedto the locking-lever for actuating the same when uncoupled from the bar.In testimony that I claim the foregoing I have hereunto set my hand, atCrandon, in the county of Forest and State of Wisconsin, in the presenceof two Witnesses.
